5. If you have given your landlord enough time to address your concerns but still no resolution, get creative. Make a video of your apartment's condition and post it on, say, YouTube or Facebook. It may even go viral, as the one made by the woman in the Fox59 report did. Your landlord can sue you for libel but not successfully if you have factual evidence.

6. Find agencies that can help you. The Marion County Health Department has an online complaint form you can fill out. The Office of the Indiana Attorney General has one, too. Also, Indiana Legal Services offers free civil legal assistance to low-income people.

7. As a last resort, move out early. If conditions have become so bad that you feel the need to move out before your lease is up, you can do so justifiably under a doctrine called constructive eviction. You may get sued for violating the terms of your lease, so make sure you have as much proof as possible. Have independent witnesses who can back your claims and are willing to testify on your behalf. Hofer said you may lose if the judge finds that the conditions aren't so bad after all, so do this only as a last resort.
